    Bigger, better, and broader in scope, the Big Book of Windows Hacks gives you everything you need to get the most out of your Windows Vista or XP system, including its related applications and the hardware it runs on or connects to. Whether you want to tweak Vista's Aero interface, build customized sidebar gadgets and run them from a USB key, or hack the "unhackable" screensavers, you'll find quick and ingenious ways to bend these recalcitrant operating systems to your will.

    The Big Book of Windows Hacks focuses on Vista, the new bad boy on Microsoft's block, with hacks and workarounds that also work for Windows XP. You can read each hack in just a few minutes, saving countless hours of searching for the right answer. The step-by-step instructions let you apply the solutions in no time. This book takes you beyond the operating system with hacks for applications like Internet Explorer 7 and Office 2007, and hardware such as the Zune, your wireless router, and the PC itself.

    The Big Book of Windows Hacks includes:

    Expanded tutorials, new background material, a series of "quick hacks", and informative sidebars

    Security hacks, including protection at wireless hotspots, hacking Vista file permissions and user account protection, and more

    Efficiency hacks, such as tweaking your PC hardware, troubleshooting hardware problems, and speeding up system performance

    Fun hacks, like building a custom Media Center PC or turning a PC into a digital video recorder

    "Beyond Windows" hacks for running Linux inside Vista, dual-booting Linux/Windows or XP/Vista, or emulate classic video games on your PC

    In all, this remarkable book contains more than 100 hacks so that the power user in you never again needs to be at the mercy of systems and hardware run by Microsoft's omnipotent Vista and XP operating systems.

  6. Pro Decrypting VBScript Viruses {Rapidshare}

    Pro Decrypting VBScript Viruses

    pro.jpg

    Author: Martini Fakhrou

    Paperback: 46 pages

    Publisher: MARTANI eXpress (April 2008)

    Language English

    ISBN-10: N/A

    ISBN-13: N/A

    Format: pdf

    Details:

    In this book, you will learn how to decrypt a VBScript and find the original source code; it will also teach you a number of techniques used by hackers to protect their source code. That may be so effective for use with your own code or your secret algorithms, which is very useful.

    This book will not talk about the virus behavior or its VBScript specified functions right now (another book will discuss the VBScript viruses behavior wait for it?, you check for other related books), it is intended to discuss the methods hackers use to obfuscate their source code so others can’t understand it. And AVs cannot just detect the threats so early.

    I gave also some examples about some easy-to-understand viruses and other algorithms I found on the web, so they can make a good base you can start from, I also mention some ways of decrypting Encoded scripts by the WSD (Windows Script Decoder), but I don’t provide any tools or real codes (you know Microsoft and the Copyrights!!!!).

    Also, this book supposes that you have a little knowledge about VBScript and scripting in general. It will not teach you VBScript, if you wish learn VBScript those books are so good to start: wrox vbscript programmer's reference or Sams VBScript WMI and ADSI Unleashed.

    Another more thing: there is no Technical Reviewer or any help from others, I wrote this book alone, if there are some errors you can understand the situation, also English is not my language, so expect lots of grammatical mistakes, your help is welcome about that of course.
